Specification of Letters Patent.

To all whont it may concern:

Be it known that I, JAMEs GEEN, a citizen of the United States, residing at Brooklyn, Kings county, New York, have invented certain new and useful Improvements in Gas- Meters, of which the following is a full, clear, and exact description.

My invention relatesto improvements in gas-meters; and it consists, broadly, in certain novel features of construction whereby many advantages are attained.

Among the advantages of my invention are to eliminate the present guides employed in the ordinary gas-meter and to that extent reduce substantially the friction which said guides caused. The construction is such also that the quantity of leather required for the bellows is substantially reduced, and said leather is so arranged that there is no friction of the same against the sides of the box or case as the bellows move in and out. Again, by reducing the amount of leather the fold therein does not encounter the product of condensation which settles to the bottom of the meter and which when absorbed by leather (as in the case of the old-type meters) results in hardening and rotting the same, causing the meter to work spasmodically or stopping it entirely. These and other advantages will be apparent to the mechanic skilled in this art from an examination of the drawings and a reading of the following description.

In the drawings, Figure 1 is a view of the front of the meter with the front and top plates removed, revealing one end of the bellows. Fig. 2 is a plan view of the meter with.

the top open, showing the usual bellows connection. Fig. 3 is a sectional view of the bellows and the adjacent parts.

1 is the case.

2 is the inlet-pipe.

3 is the outlet-pipe.

4 4 are the end disks of the bellows. 5 is the partition. 6 is a stationary ring carried by the partition and extending on each side thereof to receive the leather diaphragm, which connects the diaphragm heads or disks 4 4*, respectively, with said ring. The leather portions of said bellows are indicated at 7 7 a respectively, a short ring being provided at the edge of each head or disk 4 4" to permit the adjacent edge of the leather to be tied thereon after the usual manner.

8 8 are the carriages, respectively, for the disks. These carriages are as shown in Figs.

1 and 3, of substantial length and comprise two bridge-like side bars spaced apart and parallel with each other. 9 9 are pivots midway in said carriages 8 8*, respectively.

10 10 are what are technically termed the flags, the same being loosely pivoted to the carriages, but rigidly connected with the crank-like flag-wires 11 11 respectively. These flag-wires 1 1 1 1* formerly were straight bars; but by my improvement they are both provided with a crank. By forming the crank bend in the flag-wires it permits the head of the bellows adjacent thereto to throw out farther than was formerly the case, since said bellows-head can enter the bend of the crank. In Fig. 3 it will be seen the head 4 has receded to a position practically over the center of the axis of rotation of the flag-wire 1 1 whereas without the crank such a position would be impossible, as no clearance would be afforded. The usual link connections are provided whereby the shaft 12 may be turned. The shaft 12 carries meanswithin the inclosure-box 13 for operating the valves. (Not shown.) A description of these par ticular link-and-valve connections, as well as their operation, is'unnecessary, as the same are well understood. The link connections appear in Fig. 2 and are indicated at 14 14 and 14 14*.

On referring to Fig. 3 it will be seen that the ring 6 is substantially widerthat is, from edge to edge-relatively to the size of the diaphragm than in the commonly-known type of meter. The result is the bellows will have a relatively greater capacity. By affording the clearance in the crank portion of the flag-wires 11 11 the disks 4 4 may be so set as to have the usual stroke to and fro without encountering directly the ring 6, whereas in the old type the ring portion of the disks did encounter the ring 6, owing to lack of room, with the result that sometimes they would become locked, as it is technically termed, checking the operation of the meter and cutting off the supply. This danger, however, is avoided by my improved construction. It will be seen that While the bellows is contracting the leather will not engage the side of the case 1 until perhaps at the extreme contracted position. It will be observed that the usual guide-wire is entirely eliminated, the flags 10 10 being of sufficient height to properly support the disks 4 4 re spectively, through the medium of the broad carriages 8 8 The carriage being in the form of a bridge spanning a considerable area of each end disks or heads supports the same effectively and prevents oscillation or wabbling. As a result of the foregoing construction the advantages first referred to are attained, and in use the apparatus is more certain and positive in its action, and the life of the diaphragm is materially increased.

What I claim is 1. In a gas-meter, a diaphragm including a stationary and a movable ring, a flexible connection of material impervious to gas, a pivotally-mounted flag-wire, the intermediate portion of said flag-wire being offset to form a crank, an end disk, and a connection between the crank portion of said flag-wire and said disk, said connection including a bridge comprising two bridge members spaced apart and raised horizontally on the back of the disk, a flag-wire and a link aflixed to said flag-wire at one end and pivotally connected with said bridge members intermediate of the length of the latter.
